I've seen enough people doxxed in various capacities that there are good reasons for this in general. You won't find anything on mine... if I even have one. I've been avoiding Facebook since the days it required a .edu email to sign up, for example.

That said, I'm sure that all the politicians have people who can drum up social media followers or spread whatever message they want. I don't think there's any conspiracy to it. It's not like we've gotten rid of email spam, either. This is just an extension of that.
